NAME
wctrans - wide-character translation mapping
SYNOPSIS
#include
wctrans_t wctrans(const char *name);
DESCRIPTION
The wctrans_t type represents a mapping which can map a wide character
to another wide character. Its nature is implementation-dependent, but
the special value (wctrans_t) 0 denotes an invalid mapping. Non-zero
wctrans_t values can be passed to the towctrans(3) function to actually
perform the wide-character mapping.
The wctrans() function returns a mapping, given by its name. The set
of valid names depends on the LC_CTYPE category of the current locale,
but the following names are valid in all locales.
"tolower" - realizes the tolower(3) mapping
"toupper" - realizes the toupper(3) mapping
RETURN VALUE
The wctrans() function returns a mapping descriptor if the name is
valid. Otherwise it returns (wctrans_t) 0.
CONFORMING TO
C99.
NOTES
The behavior of wctrans() depends on the LC_CTYPE category of the cur
rent locale.
